CAR-COUPLING. 1,,

SPECIFICATION forming part of Letters Patent No. 287,749, dated October 30, 1883. i Application filed July 28, 1882 (No modeli) h To all whom it may concern Be it known .that we, WILLIAM HENRY WHITE and HIRAM F. BUDDELL, both citizens of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented a new and useful Gar-Coupling, of which the following is a specification.

Our invention is a car-coupling constructed as fully described hereinafter, whereby the automatic and positive coupling together of cars is effected with celerity and dispatch.

In the drawings, Figure 1 represents aside elevation of a car-coupling having our improvement embodied therein; Fig.2, a front elevation of Fig. 1; Fig. 3, a longitudinal section on theline 1 2, Fig. 2. Fig. 4 is"another side view. 7 p v In a box or case, T, secured to the bottom of the car is bolted the draw-head R, having .a buffer-spring interposed between its rear portion and the end of the box or case, so as to admit of a limited longitudinal play of the draw-head within the said case T. Theusual protruding portion of the draw-head is recessed for the reception of the coupling-link and has alsoavertical link-perforation, of peculiar contour, in which plays the coup; ling-link A,of the shape shown in dotted lines, Fig. 1, and full lines in Fig. 2-namely, an elongated wedge shape, with the apex at of the wedge resting in a corresponding recess in the link-perforation when the link is" in its nortending across the mal position in the draw-head; The link has also an extension or arm, b,,which extends rearward in the link-recess, and provided with an elongated slot, through which passes transversely a pin, N, secured to the sides of the draw-head, and a lip or shoulder, e, which bears (when the coupling-link rests snugly within the pin-perforation) on a pin, 0, ex-

coupling recess parallel with the pin 6. l

The front portion of the draw-head is provided on each side with curved vertical'slots f, in whichplays oneof the ends of a bar, G,

transversely arranged in the coupling-recess,

, and having its ends projecting through the slots from the exterior of each side of the draw-head, where they are connected to horis z'ontal levers K, pivoted centrally to the side of the draw-head, and the other sides of which are attached to vertical levers J ,each connected to short arms F, keyed on a shaft, 0,

journaled in brackets g, secured to face of the.

preferably located a short distance from the side of the car, so as to avoid any necessity for eration A sleeve or collar, B, centrally located on the shaft 0, turns loosely thereon, and

tached rigidly to one end of the said shaft 0, and

' dangerous proximity during the coupling op-' is cut away at h h, so as to have its end portions bear on the arm P of the said shaft 0 and is; moreover, provided. with a centrallyprojecting arm, B, connected to the coupling-- link A by means of a chain, 1'.

The operation is as' follows: Either of the levers being swung in the direction of the arrow, Fig. 3, the shaft 0 is revolved, so as to elevate its arms F,which indirectly raise. the arm B by turning the sleeve B, the couplingpin A, by reason of the'chain-connection i, being elevated in consequence. When the coupling-pin is elevated, its shoulder 6 slides on the 7 pin 0, while-the rear portion of its extension 12 moves toward the bottom of the draw-head until the pin Nin the slot 0 prevents further movement. The pin can now remain in this position, if it is desired, until the coupling operation is to occur, when the thrust or shock of the entrance of the coupling-link will be sufficient to enable the' pin to resume its original position by gravity. When the arms F or the shaft 0 are elevated by the revolution of said shaft in raising the coupling-pin, the rods J are raised therewith, moving the levers K on their pivots, so as to depress the forward ends of said levers, and likewise the transverse bar G, which is thus prevented from presenting any obstruction to the entrance .or

withdrawal of'the link, as circumstances may require. a 7

It will be apparent that by swinging either of the levers in a reverse direction to that previously described the cross-bar G can be elevated in'a corresponding degree, this move ment and that previously described enabling the said bar G to be so adjusted as to guide theentrance of the link-coupling Q at any angle.

It will'also be obvious. that by forming the coupling-pin A with the central enlargement, I

a, the pin is materially strengthened in the line of the draft, and will better resist the strain in that direction than pins usually employed.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a car-coupling, of a shaft, C, turning in brackets 011 the car above the draw-head, having arms F, and a loose collar, B, turning on the shaft 0, and having arm 13, and cut away to bear on the arms F, and connected to the coupling-link by a chain, 73, and devices for effecting the rotation of the shaft 0, substantially as set forth.

2. The combination, in a car-coupling, of the shaft 0, turning in brackets on the car above the draw-head, having arms 13, and a loose collar, 13, turning thereon, and having an arm, B, connected to the wedge-shaped pin A, substantially as set forth.

3. The combination, in a draw-head, of the shaft 0, turning in brackets on the car above the draw-head, and connected and arranged with devices when revolved to elevate the coupling-link, of rods J, connected to the centrally-pivoted levers K, which are connected with the ends of the bar G, playing in the slots f of the draw-head, substantially as and for the purpose set forth.
